Robert Lubbock Bensly (born in Eaton, Norwich, England, 24 August 1831; died in Cambridge, 23 April 1893) was an English orientalist.
His school fellows included the headmaster's grandson Henry William Brewer, later a notable architectural illustrator, the clinician and physiologist Sydney Ringer and the architect Edward Boardman.
He was a member of the Old Testament Revision Company; and accompanied Mrs. Lewis and Mrs. Gibson on the 1893 trip to Saint Catherine's Monastery in Egypt following the sisters' discovery there the previous year of a palimpsest of the Gospels in Syriac.
Bensly, together with Francis Crawford Burkitt, played an important role in deciphering the text on this second trip.
On 14 August 1860 in Halle, Bensly married Agnes Dorothee, daughter of Baron Eduard von Blomberg, who, with three children, survived him.
